Isaiah 49:4 KJV

2And he hath made my mouth like a sharp sword; in the shadow of his hand hath he hid me, and made me a polished shaft; in his quiver hath he hid me;

3And said unto me, Thou art my servant, O Israel, in whom I will be glorified.

4Then I said, I have laboured in vain, I have spent my strength for nought, and in vain: yet surely my judgment is with the LORD, and my work with my God.

5And now, saith the LORD that formed me from the womb to be his servant, to bring Jacob again to him, Though Israel be not gathered, yet shall I be glorious in the eyes of the LORD, and my God shall be my strength.

6And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.
